Jamal Musiala gave them a ninth-minute with a diving header at the back post, before Leon Goretzka, Michael Olise, Nicolas Jackson and Raphael Guerreiro scored in the second half to secure a convincing victory.

Musiala's header from a Konrad Laimer cross was Bayern's 101st league goal this season, equalling the record they set in 1971-72 for the most scored in a Bundesliga campaign.

Musiala also hit the post with a curling effort midway through the first half, before a heroic Kim Min-Jae block denied St Pauli an equaliser from one of their few sights of goal.

It took Vincent Kompany's side eight minutes after the restart to break the Bundesliga goals mark when Goretzka volleyed in the 102nd after a Joshua Kimmich free-kick was flicked on to the far post.

Just 75 seconds later France winger Olise found the bottom corner from the edge of the penalty area, before Jackson side-footed past St Pauli goalkeeper Nikola Vasilj from close range.

Guerreiro added a deserved fifth in the 89th minute after picking the pocket of a defender and slotting home.

Bayern took full advantage of Borussia Dortmund's 1-0 defeat to Bayer Leverkusen earlier on Saturday, and now hold a commanding lead over their closest rivals with just five games left to play.

Their goal difference now stands at 78, with Kompany's side having scored at least twice in 27 of their 29 league matches.

Musiala was named player of the match on just his third league start of an injury-hit campaign as he looks to earn a place in Germany's World Cup squad.

Such was the ruthlessness of Bayern's second-half attacking play, England captain Harry Kane was able to rest on the bench before the second leg of his side's Champions League quarter-final against Real Madrid on Wednesday, with the Germans 2-1 ahead.
